Getting started
From a STEP file to a PDF report. The Windows installer opens with early access.
System requirements
| Required | Recommended | |
|---|---|---|
| Operating system | Windows, 64-bit | Windows 11 |
| Memory (RAM) | 8 GB for parts up to about 50,000 elements (Free plan limit) | 16 GB for larger parts (Plus, Pro, Enterprise) |
| Processor | 64-bit x86 | 4 cores or more |
| Graphics card | Not required | NVIDIA card with CUDA support for faster flow analysis |
| Internet | Needed to sign in, for the weekly licence renewal and for AI with the included quota. Solving needs no internet. Without a connection, Dynence keeps working for your plan's offline period (14 to 45 days). | |
| Files | STEP, IGES, BREP and STL. For assemblies and for loading specific faces, use STEP. | |
What these numbers are based on
Measured on Windows on our development computer (Intel Core i5-13420H, 16 GB RAM, NVIDIA RTX 4050 6 GB), static analysis with the automatic second mesh pass that checks the result:
| Part | Elements | Time | Peak memory |
|---|---|---|---|
| Plate with hole, bending | 25,600 to 45,700 | 12 to 46 s | 1.0 to 1.9 GB |
| Stepped shaft with fillet, tension | 27,800 to 54,500 | 17 to 62 s | 1.2 to 2.5 GB |
| L bracket with a sharp inner corner | 34,200 to 48,800 | 20 to 71 s | 1.3 to 1.9 GB |
| Beam and plate, fine mesh (single pass) | 63,000 to 69,000 | 37 to 52 s | 2.3 to 2.8 GB |
Memory, not element count, is the limit. Around 150,000 elements a single run needed more than the roughly 3 GB that was free on the test machine. That is why we recommend 16 GB for the paid plans' larger mesh limits. Close other memory-heavy programs when you solve large parts.
Not yet measured, so not claimed: installer size and disk space, behaviour on Windows 10, and flow analysis times without an NVIDIA card. Without one, flow runs on the processor and is slower. We will publish these numbers once they are measured on more machines.
1. Install and sign in
- Download the installer from the link in your early-access email and run it. Dynence installs for your user account and does not need administrator rights [to be confirmed with the first installer build].
- Open Dynence and choose Sign in. Your browser opens. Sign in with Google, Microsoft or a one-time email code. If your browser is on another computer, choose Sign in with a code and type the code shown in the browser into Dynence.
- Dynence downloads a signed licence for this computer. You can see and remove your devices on the account page.
2. Your first analysis
- Open a part. Drag a STEP file onto the start screen (Drop your part here) or use Open model…. To look around first, open one of the solved examples (Open result →).
- Say what happens to it. Click the faces in the 3D view and choose what they are: a Fixed support, a force, a pressure. Or type it in plain words in the question bar, for example "the two holes are bolted, 2500 N downward on the top face". Dynence shows the setup it understood before anything is solved.
- Pick the material. Choose from the list or add your own from a datasheet.
- Solve. Dynence builds the mesh, solves, then solves once more on a finer mesh to check itself. If something important is missing, it asks before solving.
The AI question bar is optional and can be turned off in Settings. Everything above also works by clicking. See the Privacy Policy for what the AI receives.
3. Read the result and its confidence
- The answer comes first: for example the safety factor, the peak stress and where it is, the maximum displacement.
- Each result carries a High, Medium or Low confidence rating. It shows how much the peak changed between the two mesh passes.
- Sharp inner corners, edges of fixed faces and point loads are flagged: stress there depends on the mesh, so the peak value is not trustworthy. Add a fillet radius or read the value a little away from the corner.
- Ask follow-up questions in plain words: "what is the stress at this hole?", "how much more load can it take?"
4. Get the report
Choose Download report (PDF). The report lists the setup, the assumptions, the results with their confidence and the solver checks. Every report states that the verdict is a rule-based threshold and does not replace engineering judgement. Check the result before you build, certify or sell anything (Terms, section 7).
If something goes wrong
- The part does not open or the mesh fails: STEP from your CAD program works best. Dynence repairs small gaps by itself and tells you what it changed.
- The solve stops with a memory message: close other programs or use a coarser resolution. See the memory table above.
- An analysis fails unexpectedly: Dynence offers to send an error report and shows you its full content first. Nothing is sent unless you press Send.
- No internet: solving keeps working. Sign-in, licence renewal and AI with the included quota wait until you are back online.
